Hey I wanted to have a party with music and lots of people so I was woundering am I aloud to play loud music and can I set up a party tent

You can, however if you plan on having alcohol, you will need a permit for it.

Away from the lake at the north end of the park you can.

Yes in certain areas. I always notify them though. And keep in mind this is a family park so keep your music appropriate and not TOO loud. Others are trying to enjoy the park also. Enjoy your party

You can reserve a cabana and get a permit for alcohol. Just remember that its public property.

You can as long as it doesn't have profanity and as long as it's not too loud. No alcohol though.
